Strain K001 was isolated from a cyanobacterial culture derived from Abrolhos, a reef bank microbial mat (South Atlantic Ocean-Brazil). Cells of K001 are Gram stain-negative, catalase and oxidase-positive, non-motile, rod-shaped, and with or without appendages. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain K001 belongs to the genus Muricauda. The highest strain K001 16S rRNA gene identity, ANI, and dDDH, respectively, are with M. aquimarina (98.90%, 79.23, 21.60%), M. ruestringensis (98.20%, 80.82, 23.40%), and M. lutimaris (97.86%, 79.23, 22.70%). The strain grows at 15-37 °C and between 0.5 and 10% NaCl. The major fatty acids of strain K001 are iso-C15:0, iso-C15:1 G, iso-C17:0 3-OH, and summed feature 3 (C16:1 ω6c and/or C16:1 ω7c). The polar lipids are represented by phosphatidylethanolamine, three unidentified aminolipids, and three unidentified polar lipids. The major respiratory quinone is MK-6. The G+C content of the DNA of strain K001 is 41.62 mol%. Based on polyphasic analysis of strain K001, it was identified as a novel representative of the genus Muricauda and was named Muricauda brasiliensis sp. nov. The type strain is K001 (=CBMAI 2315T = CBAS 752T).

巴西鼠尾草 sp. 11 月，从形成垫子的蓝藻培养物中分离出来

菌株 K001 是从源自 Abrolhos 的蓝藻培养物中分离出来的，Abrolhos 是一种珊瑚礁微生物垫（南大西洋-巴西）。K001 的细胞是革兰氏染色阴性、过氧化氢酶和氧化酶阳性、非运动性、杆状，并且有或没有附属物。基于16S rRNA基因序列的系统发育分析表明菌株K001属于鼠尾草属。最高的菌株 K001 16S rRNA 基因同一性、ANI 和 dDDH 分别与 M. aquimarina (98.90%, 79.23, 21.60%), M. ruestringensis (98.20%, 80.82, 23.40%) 和 M. 7 lutims86 %、79.23、22.70%）。该菌株在 15-37 °C 和 0.5% 至 10% NaCl 之间生长。菌株 K001 的主要脂肪酸是 iso-C15:0、iso-C15:1 G、iso-C17:0 3-OH 和总特征 3（C16:1 ω6c 和/或 C16:1 ω7c）。极性脂质以磷脂酰乙醇胺为代表，三种未鉴定的氨基脂质和三种未鉴定的极性脂质。主要的呼吸醌是 MK-6。K001菌株DNA的G+C含量为41.62 mol%。根据菌株 K001 的多相分析，它被鉴定为鼠尾藻属的新代表，并命名为巴西鼠尾藻。十一月 类型菌株是 K001 (=CBMAI 2315T = CBAS 752T)。
